ObjectivesThis review aims to (a) identify correlates of youth sport attrition, (b) frame correlates within a multilevel model of youth sport participation (i.e., biological, intra-personal, inter-personal, institutional, community, and policy levels), and (c) assess the level of evidence for each correlate.DesignReview paper.MethodsSystematic review method.ResultsEntering relevant search terms into PubMed, PsycINFO, SPORTDiscus and Web of Knowledge databases identified 23 articles with a total of 8345 participants. Satisfactory articles largely examined sport-specific attrition and sampled youth from western countries (e.g., Canada, France, Spain, United States). Of the 141 correlates examined, most were framed at the intrapersonal (90) and inter-personal levels (43). The level of evidence for each correlate (i.e., high, low, insufficient) was systematically assessed based on the quantity and quality of supporting articles. In total, 11 correlates were categorized as having a high quality level of evidence and 10 as having a low quality. High quality correlates included, among others, age, autonomy, perceived competence, relatedness, and task climate.ConclusionsOverall, established correlates of youth sport attrition are largely social in nature. Future directions surrounding (a) the need to examine correlates at lower (i.e., biological level) and higher (i.e., institutional, community, policy) analytic levels, (b) to sample participants from more culturally diverse societies and (c) to examine sport-general attrition are offered.  相似文献

ObjectivesThe purpose of this study was to examine the effects of a peer-based mental imagery intervention on the self-determined motivation and cardio-respiratory fitness of university enrolled women.DesignRandomized controlled trial.Method43 University enrolled women were randomized to peer-mentored or peer-mentored plus mental imagery conditions while 32 completed three meetings with peer-mentors and post-testing (Mage = 19.91; SD = 1.70).ResultsSignificant improvements in cardio-respiratory endurance, ratings of perceived endurance, and self-determined motivation to exercise were observed across both study conditions. Participants assigned to the peer mentored plus mental imagery condition reported significantly greater increases in self-determined motivation to exercise at post-test compared to those in the peer-mentored condition.ConclusionsPeer-based interventions are a viable way to improve fitness and health outcomes while mental imagery appears to be associated with increases in autonomous forms of exercise motivation.  相似文献

ObjectivesWe examined (1) how psychological need fulfillment and motivation in physical education and leisure-time physical activity change during early adolescence, and (2) the degree to which need fulfillment and motivation predict trajectories of change in physical activity.DesignLongitudinal survey.MethodsStudents (N = 134, ages 10–13 years) completed surveys assessing perceived competence, autonomy, relatedness, intrinsic motivation, and identified, introjected, and external regulations in physical education, and leisure time physical activity each semester in school for 3 years.ResultsUnconditional growth models showed an average increase in physical activity. Competence also increased, while autonomy and relatedness, and identified and introjected regulation decreased. Conditional models showed that students with higher levels of autonomy, relatedness, intrinsic motivation, and identified regulation had higher levels of physical activity at baseline and throughout the study. Students with lower levels of autonomy, relatedness, intrinsic motivation, and identified regulation experienced significantly greater increases in physical activity, but these effects were very small.ConclusionsNeed fulfillment and motivation variables positively predict physical activity. While youth with lower levels of need fulfillment and motivation have lower levels of physical activity, they also tend to increase physical activity levels more across early adolescence. These associations highlight how physical education experiences in early adolescence may influence change in physical activity, and suggest efforts to foster need fulfillment and autonomous regulation in physical education may promote physical activity.  相似文献

Leader distance theory has received scant empirical attention in the extant literature; however, the “work from home” orders associated with COVID-19 have made this theory and its empirical findings highly relevant for organizations. Our study integrates leader distance theory and followership theory to understand how follower role beliefs affect follower effort, performance, and withdrawal under physical leader distance and varying conditions of leader interaction frequency. Using a three-wave survey methodology with 260 adults working remotely, our study finds that followers' levels of effort, performance, and withdrawal were contingent on leader interaction frequency. Specifically, followers with a coproduction role orientation, who see their role as more collaborative, reported higher levels of effort under conditions of high leader interaction. Furthermore, the indirect effect of coproduction on follower performance and withdrawal via effort was moderated by leader interaction frequency. The results for followers with passive role orientations, however, were in the opposite direction. These followers reported less effort when leader interaction was high, and the mediational chain predicting performance and withdrawal was contingent on leader interaction frequency. Our study contributes to the ongoing conversation about the positive and negative effects of leader distance and positions followership characteristics as important boundary conditions of distal leadership.  相似文献

In this study, prototypicality of the aggressor was tested as a group-level factor predicting social media users’ active participation in cyberaggression. Participants were exposed to a fictitious conversation, in which either a prototypical versus non-prototypical user posted an aggressive comment as a reply to a provocative comment. In line with self-categorization theory, we hypothesized that bystander participants would post an aggressive comment and rate the aggression as acceptable to a greater extent in the prototypical than in the non-prototypical condition. Furthermore, we predicted that perceived normativity of aggression would mediate the effect of prototypicality. Results supported these predictions and showed that prototypical members affect the extent to which collective aggressive behaviors in online interactions are approved and enacted. These findings highlight the importance of group-level factors in the study of cyberaggression and provide important information for understanding the psychological underpinnings of collective forms of online aggression.  相似文献

Grounded in social cognitive theory (SCT), this study sought to examine whether parents perceived social cognitive factors regarding children's physical activity (PA) behaviors were associated with preschool children's moderate-to-vigorous PA (MVPA) levels. A total of 142 Hong Kong parent-child pairs from five preschools/childcare centers completed all assessments in the cross-sectional study. Children’s (42% girls; mean age = 4.52 ± 0.67 years) PA was measured through accelerometers. Parents (74% mothers; mean age = 37.38 ± 4.63 years) completed a paper-based questionnaire assessing the social cognitive factors on their children’s PA participation. The data were analyzed using latent variable structural equation modeling. Findings revealed that the model showed acceptable fit with the data: χ2 (23) = 38.14, p = .025, χ2/df = 1.66, CFI = 0.955, TLI = 0.929, RMSEA = 0.068, 90% CI [0.025, 0.106], and SRMR = 0.072. The model accounted for 39.1% of the variance in the PA behavior of preschool-aged children. Structural equation modelling revealed parental self-efficacy (β = 0.29, 95% CI [0.95, 0.49]) and goal setting (β = 0.25, 95% CI [0.06, 0.44]) were directly associated with children’s MVPA. Outcome expectations (β = 0.09, 95% CI [0.01, 0.03]) and goal setting (β = 0.18, 95% CI [0.05, 0.32]) mediated the association between parental self-efficacy and children’s MVPA. Indirect associations of parental self-efficacy from setting goals via parental support (β = 0.15, 95%CI [0.02, 0.30]) and perceived barriers (β = 0.15, 95% CI [0.05, 0.28]) were uncovered. Results supported the use of SCT in understanding how the parents perceived social cognitive factors predict the PA behaviors of young children. This study provides insight into whether these theoretical variables could be modified or promoted in future intervention programs. Enhancing parents’ abilities to ensure preschool-aged children are physically active is of great importance given the global decline in PA among children.  相似文献

There are currently no published studies that investigate or discuss the cultural responsiveness of Dialectical Behavior Therapy (DBT) to the needs of Black/African-American clients. In addition, no published scholarly works offer guidance to therapists on how to practice antiracism within the context of delivering evidence-based treatment. Methods for developing a culturally responsive antiracist treatment are discussed within a dialectical framework and from the perspective of critical race psychology. We propose that an antiracist adaptation to DBT is needed to correct for context minimization errors in the DBT model that create an invisibility of racism. Recommendations are made for an additional DBT Therapist Agreement that encourages labeling and targeting therapist treatment-interfering racist behavior. An additional Therapist Consultation Agreement is also proposed to guide therapist antiracist advocacy and functional validation for Black/African-American clients. The DBT technology is used in conjunction with other multicultural theoretical models to recommend strategies for developing White DBT therapists’ antiracist competencies. Future directions for developing critical race psychological research are discussed.  相似文献

压力是对潜在威胁性事件产生的生理与心理反应。正念通过专注当下并保持接纳的态度缓解压力。然而以往关于正念缓解压力的研究并没有明确具体的机制,且忽略了正念影响压力过程中的复杂性与多样性。监控与接纳理论通过解构监控与接纳成分,更加清晰地呈现了正念的作用机制,因此本文依据监控与接纳理论,梳理正念对压力的影响效果及其心理神经机制。未来的研究在探讨正念通过监控与接纳成分影响压力的同时应重点关注监控作用效果与机制;重视压力刺激与压力评估的重要性;设计新的实验范式,直接探究正念监控与接纳对压力影响的心理与神经机制。  相似文献

计算机化分类测验(Computerized Classification Testing, CCT)能够高效地对被试进行分类, 已广泛应用于合格性测验及临床心理学中。作为CCT的重要组成部分, 终止规则决定测验何时停止以及将被试最终划分到何种类别, 因此直接影响测验效率及分类准确率。已有的三大类终止规则(似然比规则、贝叶斯决策理论规则及置信区间规则)的核心思想分别为构造假设检验、设计损失函数和比较置信区间相对位置。同时, 在不同测验情境下, CCT的终止规则发展出不同的具体形式。未来研究可以继续开发贝叶斯规则、考虑多维多类别情境以及结合作答时间和机器学习算法。针对测验实际需求, 三类终止规则在合格性测验上均有应用潜力, 而临床问卷则倾向应用贝叶斯规则。  相似文献

The Australian population is experiencing a rapid ageing of the population, and as such, an increased need for gerontological practitioners in the helping professions will continue to grow. Terror management theory (TMT), which was used to frame this study, posits that because of the fact that humans are aware of their own mortality, they are compelled to avoid the anxiety associated with it. Personal ageing and interaction with older adults may be reminders of the unavoidable decline and death that faces us all. The purpose of this study is to examine comfort in spending time with older adults amongst students, academic teaching staff, and practitioners in the fields of psychology and social work. We sought to determine if TMT helped predict fear of being with older adults. Ageism, contact with older adults, and known demographic factors associated with attitudes towards older adults were also examined. Hierarchical multiple regression explained nearly 46% of the variance in comfort with older adults and indicated that fear of ageing, positive ageism, negative ageism, contact with older adults, and sex were significant predictors. Educational efforts aimed at addressing beliefs about ageing and older adults may contribute to further comfort in working with older adults.  相似文献
